Principal Full-Stack & AI Architect

SaaS

Apr 2026 - Present • 4 mos

Architected and developed an enterprise-grade, multi-tenant SaaS hospitality ecosystem managing omnichannel ordering, kitchen operations, and third-party logistics. Engineered a comprehensive suite of applications including Next.js Progressive Web Apps (PWAs), native Android Kiosk POS systems, and real-time Kitchen Display Systems (KDS). Key Technical Achievements: - Autonomous AI Ingestion: Integrated a Twilio-backed AI Voice Agent (IVR) capable of processing complex natural-language phone orders, syncing dynamically with a real-time "Living Menu" database to prevent inventory collisions. - Complex Revenue Routing: Engineered a Stripe Custom Connect payment infrastructure to handle automated, real-time multi-party fund splits across merchants, platform commissions, and third-party logistics fleets. - Multi-Tier Dispatch Orchestration: Built an advanced 5-tier dispatch routing algorithm (In-Store, WeDrop, Nash Network) featuring geofenced GPS tracking and strict, hardware-enforced Proof of Delivery (Photo-Lock) QA gates. - Real-Time System Synchronization: Deployed highly available WebSocket architecture to synchronize data instantaneously across POS terminals, Waiter Pads, KDS screens, and external HubRise marketplace webhooks (Uber Eats, Deliveroo).

Lead 3D Web Developer

Ecommerce • Freelance

Jan 2026 - Feb 2026 • 1 mo

Architected and developed a high-performance B2B 3D configurator for custom product ordering. Built from the ground up using React 18, React Three Fiber (R3F), and Tailwind CSS, allowing clients to customize complex physical properties with real-time 3D visualization. Key Technical Achievements: - Zero-Load Texturing: Engineered a dynamic 3D rendering pipeline using procedural HTML5 Canvas textures, completely eliminating network load for image assets. - Advanced State Management: Built a robust, heavily memoized state system (useMemo/useCallback) for real-time scaling, pricing logic, and strict B2B validation constraints. - Dynamic Quoting System: Integrated client-side PDF generation (jsPDF) that captures live WebGL canvas snapshots for instant, professional B2B quoting. - Optimized UX/UI: Designed a responsive, split-screen interface with Framer Motion animations and preloaded GLTF assets for zero-latency interactions.
